    Chips curling down and back in, and impinging on the bottom edge of the insert?

    But, why is wear at the bottom of the insert a problem? There's no cutting happening there. Or, are the inserts...

    Pretty sure the "N" in GTN means neutral. Search for "GTR" or "GTL" for handed inserts.

    Do your .3mm - .9mm drills have same-size shanks, or are they on 3mm or maybe 1/8" shanks? Most of the high-quality small drills I have are on upsized shanks.

    .3mm drill on a .3mm shank would be a...

    Yes, this. I think you could hold 3 of your pucks in a pair of standard 8" Versa Grip jaws, since they have 9 pockets across 8".

    Gotta be a little careful gripping 3 steel blanks at a time...

    Not necessarily. You can probably run the saw just fine with a VFD, and you get easy variable speed control as a bonus.

    You have to spot drill one way or the other, right? No way would I try to start an 8xD drill without something already there. So instead of spot drilling with a spot drill, spot drill with a stubby...

    Castings maybe, or a short-run custom extrusion?

    Anyway, it has been, IME, darn hard to get a consistently clean cut in 6061 without some lube, even a dab of WD40.

    I agree. I'm already close to the tipping point with MC yearly maintenance fees, given the alternatives.

    Titanium's yield is very close to its tensile, so it breaks if you go much past its yield point. A more ductile material like stainless steel has a much larger yield <> tensile gap, so it is not as...

    Mine is a 2017. Start and stop PSI's are about the same as yours.

    Ida Know, but maybe they added run-on time because they were seeing corrosion issues in the air end when cycle times were short?...

    If you don't need super-low axial runout, straightforward to simply drill and tap a 1/2" stainless ball. I did a few 100 of these some years ago. Definitely not rocket science and not $20 ;).
